I fucked my ex wife’s sister about 6 months after we got married. She came to stay with us because of a bad break-up. Every morning she would get ready in the closet nearest to me. We locked eyes every now and then, she knew what she was doing. She ran out into the living room one morning and pulled her pants down for no reason, attempting to be silly. I laughed and was hard as a rock so I grabbed her by the neck and swung her mouth towards my cock. It was very fast. I didn’t think about it. I fucked her mouth hard for a couple of minutes and then she stopped me and took off her shirt. I fucked my wife’s sister in the living room, fucked her without a condom, and came inside of her.
